FIELD OF INVENTION

The present invention relates to the use of compounds of general formula (I) for preparing a medicament intended to inhibit monoamine oxydases (MAO) and/or lipidic peroxidation and/or to act as modulators of the sodium channels. A subject of the invention is also, as medicaments, the compounds of general formula (II) defined hereafter. Moreover it relates to new compounds of general formula (III).

BACKGROUND

The compounds mentioned above often present 2 or 3 of the activities mentioned above, which confer advantageous pharmacological properties on them.

In fact, taking into account the potential role of the MAO's and ROS's (“reactive oxygen species”, at the origin of lipidic peroxidation) in physiopathology, the new described derivatives corresponding to general formula (I) can produce beneficial or favorable effects in the treatment of pathologies where these enzymes and/or these radicular species are involved. In particular:

-   -   disorders of the central or peripheral nervous system such as         for example neurological diseases where Parkinson's disease,         cerebral or spinal cord traumatisms, cerebral infarction, sub         arachnoid hemorrhage, epilepsy, ageing, senile dementia,         Alzheimer's disease, Huntington's chorea, amyotrophic lateral         sclerosis, peripheral neuropathies, pain can in particular be         mentioned;     -   schizophrenia, depressions, psychoses;     -   disorders of the memory and the humour;     -   pathologies such as for example migraine;     -   behavioural disorders, bulimia and anorexia;     -   auto-immune and viral diseases such as for example lupus, AIDS,         parasitic and viral infections, diabetes and its complications,         multiple sclerosis.     -   addiction to toxic substances;     -   proliferative and inflammatory pathologies;     -   and more generally all the pathologies characterised by an         excessive production of ROS's and/or participation of MAO's.

In all of these pathologies, experimental evidence exists which demonstrates the involvement of ROS's (Free Radic. Biol. Med. (1996) 20, 675-705; Antioxid. Health. Dis. (1997) 4 (Handbook of Synthetic Antioxidants), 1-52) as well as the involvement of MAO's (Goodman & Gilman's: The pharmacological basis of therapeutics, 9th ed., 1995, 431-519).

The advantage of a combination of the inhibitory activities of MAO and inhibition of lipidic peroxidation is for example well illustrated in Parkinson's disease. This pathology is characterized by a loss of dopaminergic neurons of the nigrostriatal route the cause of which would in part be linked to an oxidizing stress due to ROS's. The exogenic dopamine from L Dopa is used in therapeutics in order to maintain sufficient levels of dopamine. MAO inhibitors are also used with L Dopa to avoid its metabolic degradation but do not act on the ROS's. Compounds which act both on MAO's and ROS's will therefore have a certain advantage.

Moreover, the character of the modulator of the sodium channels is very useful for therapeutic indications such as:

-   -   the treatment or prevention of pain, and in particular:         -   post-operative pain,         -   migraine,         -   neuropathic pain such as trigeminal neuralgia, post-herpetic             pain, diabetic neuropathies, glossopharyngeal neuralgias,             secondary radiculopathies and neuropathies associated with             metastatic infiltrations, adiposis dolorosa and pain             associated with burns,         -   central pain as a result of vascular cerebral accidents,             thalamic lesions and multiple sclerosis, and         -   chronic inflammatory pain or pain linked to a cancer;     -   the treatment of epilepsy;     -   the treatment of disorders linked to neurodegeneration, and in         particular:         -   vascular cerebral accidents,         -   cerebral traumatism, and         -   neurodegenerative diseases such as Alzheimer's disease,             Parkinson's disease and amyotrophic lateral sclerosis;     -   the treatment of bipolar disorders and irritable colon syndrome.

The concrete advantages of the presence in a compound of at least one of these activities is therefore clearly apparent from the above.

The European Patent Application EP 432 740 describes derivatives of hydroxyphenylthiazoles, which can be used in the treatment of inflammatory diseases, in particular rheumatic diseases. These derivatives of hydroxyphenylthiazoles show properties of trapping free radicals and inhibitors of the metabolism of arachidonic acid (they inhibit lipoxygenase and cyclooxygenase).

Other derivatives of hydroxyphenylthiazoles or hydroxyphenyloxazoles are described in the PCT Patent Application WO 99/09829. These have analgesic properties.

A certain number of derivatives of imidazoles with close or identical structures to those of the compounds corresponding to general formula (I) according to the invention have moreover been described by the Applicant in the PCT Patent Application WO 99/64401 as agonists or antagonists of somatostatin. However, said derivatives of imidazoles have therapeutic properties in fields different from those indicated above (suppression of the growth hormone and the treatment of acromegalia, treatment of the recurrence of stenosis, inhibition of the secretion of gastric acid and prevention of gastrointestinal bleeding in particular).

Moreover, the compounds of general formula (A1)

in which

-   R1 represents one of the aryl, heteroaryl, aralkyl or cycloalkyl     radicals optionally substituted by one to three substituents chosen     independently from a halogen atom, the CF₃, CN, OH, alkyl or alkoxy     radical, SO₂R9 with R9 representing NH₂ or NHCH₃; -   X represents NR2, R2 representing H or alkyl; -   Y represents N or CR3; -   Z represents CR3 or N; -   on the condition however that Y and Z are not both CR3 or N at the     same time; -   R3 represents H, alkyl, halogen, hydroxyalkyl or phenyl optionally     substituted by 1 to 3 substituents chosen from H, CF₃, CN, SO₂NH₂,     OH, alkyl or alkoxy; -   m represents 0, 1 or 2; -   R4 represents H or alkyl; -   when Z represents CR3, then R3 and R4 can also represent together     —(CH₂)_(n1)— with n1 an integer from 2 to 4 or R2 and R4 can also     represent together —(CH₂)_(n2)— with n2 an integer from 2 to 4; -   R5 and R6 represent independently H, alkyl, alkoxy, aryl or aralkyl; -   NR5R6 can also represent together (in particular):     -   the optionally substituted 2-(1,2,3,4-tetrahydroquinolyl)         radical,     -   a

radical in which R7 represents one of the phenyl, benzyl or phenethyl radicals in which the phenyl ring can be substituted;

-   -   a

radical in which p is an integer from 1 to 3,

-   W is N and R8 represents H, CF₃, one of the phenyl, pyridyl or     pyrimidinyl radicals optionally substituted once to twice by     radicals chosen from halogen, OH, alkyl or alkoxy, or -   W is CH and R8 represents phenyl optionally substituted or aralkyl     optionally substituted on the aryl group; -   have been described in the PCT Patent Application WO 96/16040 as     partial agonists or antagonists of the dopamine sub-receptors of the     brain or as prodrug forms of such partial agonists or antagonists.     Therefore these compounds would have useful properties in the     diagnosis and treatment of affective disorders such as schizophrenia     and depression as well as certain disorders of movement such as     Parkinson's disease.

It has also been described in the PCT Patent Application WO 98/27108 that certain amides of general formula (A2)

in which:

-   R1 represents in particular an alkyl, optionally substituted phenyl     or optionally substituted heterocyclic aryl radical; -   R2 represents H or phenylalkyl; -   R4 represents H, quinolyl, 3-4-methylenedioxyphenyl or one of the     phenyl or pyridyl radicals optionally substituted, by a radical or     radicals chosen in particular from alkyl, alkoxy, alkylthio,     optionally protected hydroxy, amino, alkylamino, dialkylamino; -   R5 represents H or an imidazolyl, phenyl, nitrophenyl, phenylalkyl     radical, or also a —CO—N(R7)(R8) radical, in which R7 and R8     represent independently H, phenyl, phenylalkyl, alkyl or alkoxy; -   or R4 and R5 in combination form a group of formula —CH═CH—CH═CH—; -   Y is a phenylene radical substituted by a phenyl, phenoxy or     phenylalkoxy radical, or a group of formula —CH(R3)—, in which R3     represents H or a radical of formula —(CH₂)_(n)—R6, in which R6     represents an optionally protected hydroxy, acyl, carboxy,     acylamino, alkoxy, phenylalkoxy, alkylthio, optionally substituted     phenyl, optionally substituted pyridyl, pyrazinyl, pyrimidinyl,     furyl, imidazolyl, naphthyl, N-alkylindolyl or     3,4-methylenedioxyphenyl radical and n is an integer from 0 to 3; -   R2 and R3 taken together with the carbon atoms which carry them can     form a phenyl group; -   X represents S or NR9; -   R9 representing H, an alkyl or cycloalkyl radical, or also a benzyl     radical optionally substituted once on its phenyl part by H, alkyl     or alkoxy; -   are inhibitors of the NO synthases and can be used to treat diseases     which include in particular cardiovascular or cerebral ischemia,     cerebral hemorrhage, disorders of the central nervous system,     Alzheimer's disease, multiple sclerosis, diabetes, hepatitis,     migraine, rheumatoid arthritis and osteoporosis.

In a different field, the Applicant has itself previously described in the PCT Patent Application WO 98/58934 derivatives of amidines having the ability to inhibit NO synthases and/or lipidic peroxidation.

The Applicant has now unexpectedly discovered that certain intermediates of the first stages of synthesis of the amidines described in the PCT Patent Application WO 98/58934, and more generally certain derivatives of heterocycles with five members, namely the products of general formula (I) defined hereafter, have at least one of the three properties chosen from the following properties (and often even two of these three properties even sometimes all three at the same time):

-   -   MAO inhibition properties;     -   lipidic peroxidation inhibition properties; and     -   properties of modulating the sodium channels.

These advantageous properties offer the advantage of opening up numerous uses for such compounds, in particular in the treatment of neurodegenerative diseases, and in particular those indicated previously, of pain or of epilepsy.

According to preferred variants of the invention, these compounds have at least two of the activities mentioned above. In particular, they inhibit both the MAO's and trap the ROS's or they will have both an antagonist activity vis-à-vis the sodium channels and a trapping activity on the ROS's. In certain cases, the compounds of general formula (I)_(G) or (I) even combine the three activities.

This allows the compounds of general formula (I)_(G) or (I) to be of use in the treatment of the diseases mentioned previously such as being linked to MAO's, to lipidic peroxidation and to the sodium channels.

According to a more particular variant of the invention, the compounds of the invention of general formula (I) as defined previously in which:

Het is such that the compounds of general formula (I) correspond to one of the general sub-formulae (I)₁ and (I)₂ in which X represents NH or S or general sub-formula (I)₃ in which Y represents O;

-   A represents a

radical in which Q represents OH, two of the R¹⁹, R²⁰ and R²¹ radicals represent an alkyl radical and the third represents a hydrogen atom,

More preferentially, the compounds of general formula (I) which can be used to prepare a medicament intended both to inhibit MAO's and lipidic peroxidation and to modulate the sodium channels will be such that:

Still for the compounds of general formula (I) which can be used to prepare a medicament intended both to inhibit the MAO's and lipidic peroxidation and to modulate the sodium channels, n will preferably represent 0 when Het is such that the compounds of general formula (I) correspond to general sub-formula (I)₁ in which X represents S and preferably 1 when Het is such that the compounds of general formula (I) correspond to general sub-formula (I)₃ in which Y represents O.

In particular, the compounds of Examples 1, 3, 6, 24, 26, 28 and 29 (sometimes described in the form of salts) or their pharmaceutically acceptable salts will be preferred if one wishes to prepare a medicament intended both to inhibit MAO's and lipidic peroxidation and to modulate the sodium channels.

These compounds (and more     particularly those wherein R⁴⁶ is —COOR⁵¹′), will be particularly     preferred due to their sodium channel modulating activity.     Preferably, these compounds will be such that n is an integer from 0     to 2, in particular such that n is 0 or 1 (and more preferably 1).

The preparations of the other compounds of the invention which correspond to general formulae (I), (II) and (III) are carried out in a similar fashion to those described in the PCT Patent Application WO 98/58934 (cf. in particular on pages 39 to 45 of this document the syntheses of intermediates of general formulae (XXV) and (XXVIII)) or according to the procedures described hereafter.

Furthermore, the compounds of general formula (I)_(G) or (I′) are prepared in a similar manner to the compounds of general formula (I); in other words, the teachings of the following disclosure for the compounds of general formula (I) can generally be extended to the synthesis of the compounds of general formula (I)_(G) or (I′). The same applies mutatis mutandis to the compounds of general formula (III)_(G) and (III).

Preparation of the Compounds of General Formula (I)

The compounds of general formula (I) can be prepared by the 8 synthesis routes illustrated below (Diagram 1) starting from the intermediates of general formula (IV), (V), (VI), (VII), (VIII), (IX), (X) and (I)a in which A, B, Ω, R¹, R², Het and n are as defined above, L is a parting group such as for example a halogen, Alk is an alkyl radical, Gp is a protective group for an amine function, for example a 2-(trimethylsilyl)ethoxymethyl (SEM) group, and Gp′ a protective group for an alcohol function, for example a group of benzyl, acetate or also silyl type such as tert-butyldimethylsilyl, and finally Λ represents a bond or a —(CH₂)_(x)—, —CO—(CH₂)_(x)—, —(CH₂)_(y)—O— or —C(═NH)— radical. Of course, a person skilled in the art can choose to use protective groups other than Gp and Gp′ from those which are known, and in particular those mentioned in: Protective groups in organic synthesis, 2nd ed., (John Wiley & Sons Inc., 1991).

Route 1: Het is Imidazole and Ω is NR⁴⁶R⁴⁷ but not a Radical of Carbamate Type

The amines and carboxamides of general formula (I), Diagram 2, in which A, B, R¹, R², R⁴⁶, R⁴⁷, Het and n are as defined above, are prepared by deprotection for example, in the case where Gp represents SEM, with tert-butylammonium fluoride (TBAF) in THF, of the amine of general formula (IV) in order to release the amine of the heterocycle of the compound of general formula (I). The protected amines of general formula (IV) are accessible by a general synthesis route described in Biorg. and Med. Chem. Lett., 1993, 3, 915 and Tetrahedron Lett., 1993, 34, 1901 and more particularly in the PCT Patent Application WO 98/58934.

Route 2: Het is Imidazole, Oxazole or Thiazole and Ω is NR⁴⁶R⁴⁷

The amines and carboxamides of general formula (I), Diagram 3, in which A, B, R¹, R², R⁴⁶, Het, g, k and n are as defined above, Δ represents an alkyl, cycloalkylalkyl, arylalkyl, aryl, allenyl, allenylalkyl, alkenyl, alkynyl, cyanoalkyl or hydroxyalkyl radical and Δ′ represents an alkyl, cycloalkylalkyl, arylalkyl or aryl radical when g or k do not represent 0, or Δ′ represents an alkyl, cycloalkylalkyl, arylalkyl radical or an aryl radical preferably deactivated (i.e. an aryl radical substituted by an electron attractor group such as for example a nitro or cyano group) when g or k represents 0, are prepared by condensation of the amines of general formula (V) with carboxylic acids (or the corresponding acid chlorides) of general formula (XII) under standard conditions of peptide synthesis, with the aldehydes of general formula (XII) in the presence of a reducing agent such as sodium triacetoxyborohydride or sodium borohydride, in a lower aliphatic alcohol such as methanol and optionally in the presence of molecular sieves, or with halogenated derivatives (Hal=halogen atom) of general formula (XI). In particular, when Δ represents an allenyl, allenylalkyl, alkenyl, alkynyl, cyanoalkyl or hydroxyalkyl radical, the compounds of general formula (V) are converted to the corresponding compounds of general formula (I) by reaction with the halogenated derivatives of general formula (XI) in a solvent such as acetonitrile, dichloromethane or acetone and in the presence of a base such as for example triethylamine or potassium carbonate at a temperature comprised between ambient temperature and the reflux temperature of the solvent.

The derivatives of general formula (V) are in particular accessible by a general synthesis route described in Biorg. and Med. Chem. Lett., 1993, 3, 915 and Tetrahedron Lett., 1993. 34, 1901, and more particularly in the Patent Application WO 98/58934. When R⁴⁶=H, the compounds of general formula (V) can be prepared, for example, according to a protocol described in the Patent Application WO 98/58934 (using the appropriate amino acid in place of N-Boc-sarcosinamide).

In the particular case where R⁴⁷ represents a cycloalkyl radical, the amines of general formula (I), Diagram 3a, in which A, B, R¹, R², R⁴⁶, Het and n are as defined above and represents an integer from 0 to 4 are prepared by condensation of the amines of general formula (V) with the cycloalkylketones of general formula (XIV) in the presence of a reducing agent such as sodium triacetoxyborohydride or sodium borohydride in a lower aliphatic alcohol such as methanol and optionally in the presence of molecular sieves at ambient temperature.

The sulphonamides of general formula (I), Diagram 3b, in which A, B, R¹, R², R⁴⁶, Het and n are as defined above, R⁴⁷ represents an —SO₂-Δ radical and Δ represents an alkyl, cycloalkyl, cycloalkylalkyl or arylalkyl radical, are prepared by condensation of the amines of general formula (V) with the sulphochlorides of general formula (XV) under standard conditions, for example in a solvent such as dimethylformamide at ambient temperature.

The ureas of general formula (I), Diagram 3c, in which A, B, R¹, R², R⁴⁶, Het and n are as defined above, R⁴⁷ represents a —CO—NH-Δ radical and Δ represents an alkyl, cycloalkyl, cycloalkylalkyl or arylalkyl radical, are prepared by reaction of the amines of general formula (V) with the isocyanates of general formula (XVI) in an inert solvent such as dichloromethane or 1,2-dichloroethane.

Route 3: Het is Oxazole or Thiazole, R¹ and R² are both H and Ω is OH.

The alcoholic derivatives of general formula (I), Diagram 4, in which A, B, Het and n are as defined above and R¹ and R² are hydrogen atoms are obtained by reduction of the acids or esters of general formula (VI) (accessible by a general synthesis route described in J. Med. Chem., 1996, 39, 237-245 and the PCT Patent Application WO 99/09829). This reduction can, for example, be carried out by the action of boron hydride or lithium aluminium hydride or also diisobutylaluminium hydride in an aprotic polar solvent such as tetrahydrofuran.

Route 4: Het is Oxazole or Thiazole and Ω is NR⁴⁶R⁴⁷.

The amines of general formula (I), Diagram 5, in which A, B, R¹, R², R⁴⁶, R⁴⁷, Het, and n are as defined above, are prepared by condensation of the primary or secondary amines of general formula R⁴⁶—NHR⁴⁷ with the compounds of general formula (VII) (in which L preferably represents a halogen atom Hal, but can also represent a mesylate or tosylate group) according to a general synthesis route described in J. Med. Chem., 1996, 39, 237-245 and the PCT Patent Application WO 99/09829 or the U.S. Pat. No. 4,123,529. This synthesis route can in particular be used when R⁴⁶ and R⁴⁷ taken together form with the nitrogen atom which carries them a non-aromatic heterocycle with 4 to 8 members. The reaction typically takes place in an anhydrous solvent (for example dimethylformamide, dichloromethane, tetrahydrofuran or acetone) in the presence of a base (for example Na₂CO₃ or K₂CO₃ in the presence of triethylamine), and preferably while heating.

Route 5: Het is Imidazole and Ω is a Radical of Carbamate Type

When Ω is a radical of carbamate type, the acids of general formula (VIII) can be cyclized in the form of derivatives of imidazoles of general formula (I), Diagram 6, by the addition of caesium carbonate followed by a condensation with an α-halogenoketone of formula A-CO—CH(B)—[Br, Cl] followed by the addition of a large excess of ammonium acetate (for example 15 or 20 equivalents per equivalent of acid of general formula (VIII)). This reaction is preferably carried out in a mixture of xylenes and while heating (one can also, if appropriate, simultaneously eliminate the water formed during the reaction).

Route 6: Het is Imidazole, Oxazole or Thiazole and Ω is NR⁴⁶R⁴⁷

When Ω is an NR⁴⁶R⁴⁷ radical in which R⁴⁷ is a radical comprising a termination of aminophenylene, alkylaminophenylene or dialkylaminophenylene type, the compounds of general formula (I), in which A, B, Het, n, R¹, R² and R⁴⁶ are as defined above and A represents a bond or a —(CH₂)_(x)—, —CO—(CH₂)_(x)—, —(CH₂)_(y)—O— or —C(═NH)— radical, x and y being integers from 0 to 6, can be obtained, Diagram 7, by reduction of the compound of general formula (IX), for example by the action of hydrogen in the presence of a catalyst of palladium on carbon type in a solvent such as for example methanol, ethanol, dichloromethane or tetrahydrofuran. Reduction of the nitro function can also be carried out, for example, by heating the product in an appropriate solvent such as ethyl acetate with a little ethanol in the presence of SnCl₂ (J. Heterocyclic Chem. (1987), 24, 927-930; Tetrahedron Letters (1984), 25 (8), 839-842) or in the presence of SnCl₂/Zn (Synthesis. (1996), 9, 1076-1078), using NaBH₄—BiCl₃ (Synth. Com. (1995) 25 (23), 3799-3803) in a solvent such as ethanol, or then by using Raney Ni with hydrazine hydrate added to it (Monatshefte für Chemie, (1995), 126, 725-732), or also using indium in a mixture of ethanol and ammonium chloride under reflux (Synlett (1998) 9, 1028).

When R⁴⁷ is a radical of aminophenylene, alkylaminophenylene or dialkylaminophenylene type (Alk and Alk′ are identical or different alkyl radicals), the compound of general formula (IX) is reduced in order to produce the aniline derivative of general formula (I) and optionally mono- or di-alkylated according to standard reactions known to a person skilled in the art. The mono-alkylation is carried out by reducing amination with an aldehyde or by a nucleophilic substitution by reaction with an equivalent of halogenoalkyl Alk-Hal. A second alkylation can then be carried out if appropriate using a halogenoalkyl Alk′-Hal.

In the particular case where Alk=Alk′=—CH₃ and where Λ does not represents —CH₂—, the nitro derivative of general formula (IX) will be treated with suitable quantities of paraformaldehyde under a flow of hydrogen in a solvent such as ethanol and in the presence of a catalyst of palladium on carbon type (Diagram 7a).

Route 7: Het is Imidazole, Oxazole or Thiazole and Ω is OH

This route can be used when Ω is OH. Contrary to route 3, R¹ and R² cannot be hydrogen atoms. In this case, the compounds of general formula (I) can be obtained, Diagram 8, by deprotection of the protected alcohol of general formula (X).

In the case where Gp′ is a protective group of silyl type, the deprotection can be carried out, for example, by adding tetra-tert-butylammonium fluoride in a solvent such as tetrahydrofuran. In the case where Gp′ is a protective group of benzyl type, the deprotection will be carried out by hydrogenation in a solvent such as for example methanol, ethanol, dichloromethane or tetrahydrofuran. In the case where Gp′ is a protective group of acetate type, the deprotection can be carried out, for example, using sodium or potassium carbonate in an alcoholic solvent such as methanol. For other cases, a person skilled in the art will usefully consult the following document: Protective groups in organic synthesis, 2nd ed., (John Wiley & Sons Inc., 1991).

Route 8: Het is Imidazole, Oxazole or Thiazole and Ω is OR⁴⁸ with R⁴⁸H

The compounds of general formula (I) in which Ω is an OR⁴⁸ radical with R⁴⁸H are obtained, for example, Diagram 9, from alcohols of general formula (I) a (which are compounds of general formula (I) as defined previously in which Q represents OH) by reacting the latter with a halide of general formula R⁴⁸—Hal (Hal=Br, Cl or I) in a solvent such as dichloromethane, acetonitrile, anhydrous tetrahydrofuran or anhydrous ether and in the presence of a base such as potassium or sodium carbonate, sodium hydride or triethylamine.

In the case where the A, B, R¹ and R² radicals contain alcohol, phenol, amine or aniline functions, it may be necessary to add protection/deprotection stage for these functions according to standard methods known to a person skilled in the art (stages not represented in Diagram 9).

Preparation of the Synthesis Intermediates Preparation of the Imidazoles and Thiazoles of General Formula (V) General Outline

The non-commercial ketonic derivative of general formula (V.i) or (V.i)₂ in which A and B are as defined in general formula (I) is converted, Diagram 3.1, to the corresponding α-bromo-ketone of general formula (V.ii) or (V.ii)₂ by reaction with a bromination agent such as CuBr₂ (J. Org. Chem. (1964), 29, 3459), bromine (J. Het. Chem. (1988), 25, 337), N-bromosuccinimide (J. Amer. Chem. Soc. (1980), 102, 2838) in the presence of acetic acid in a solvent such as ethyl acetate or dichloromethane, HBr or Br₂ in ether, ethanol or acetic acid (Biorg. Med. Chem. Lett. (1996), 6(3), 253-258; J. Med. Chem. (1988), 31(10), 1910-1918) J. Am. Chem. Soc. (1999), 121, 24) or also using a bromination resin (J. Macromol. Sci. Chem. (1977), A11, (3) 507-514). In the particular case where A is a p-dimethylaminophenyl radical, it is possible to use the operating method appearing in the publication Tetrahedron Lett., 1998, 39 (28), 4987. The amine of general formula (V) is then obtained according to the procedures shown in Diagrams 3.2 (imidazoles) and 3.3 (thiazoles) hereafter.

Alternatively to the synthesis shown in Diagram 3.1, a person skilled in the art can, if appropriate, use an α-chloro-ketone in place of an α-bromo-ketone.

Obtaining the Imidazoles of General Formula (V)

The acid of general formula (V.iii), in which Gp represents a protective group for an amine function, for example a protective group of carbamate type, is treated, Diagram 3.2, with Cs₂CO₃ in a solvent such as methanol or ethanol. The α-halogeno-ketone of general formula (V.ii) in an inert solvent such as dimethylformamide is added to the caesium salt recovered. The intermediate ketoester is cyclized by heating to reflux in xylene (mixture of isomers) in the presence of a large excess of ammonium acetate (15 or 20 equivalents for example) in order to produce the imidazole derivative of general formula (V.iv) (the water formed being optionally eliminated during the reaction).

In the case where R³⁸ is not H, the amine function of the imidazole ring of the compound of general formula (V.iv) is substituted by reaction with the halogenated derivative R³⁸—Hal (Hal=halogen atom); the protected amine function is then deprotected under standard conditions (for example: trifluoroacetic acid or HCl in an organic solvent when it is a protective group of carbamate type, or also hydrogenation in the presence of palladium on carbon when the protective group is a benzyl carbamate).

Obtaining the Thiazoles of General Formula (V) Intended for the Preparation of Compounds of General Formulae (I)₁ or (I)₂:

The thiocarboxamide of general formula (V.v), in which Gp represents a protective group for an amine function, for example a protective group of carbamate type, obtained for example by reaction of the corresponding carboxamide with Lawesson reagent or with (P₂S₅)₂, is reacted, Diagram 3.3, with the α-bromo-ketone of general formula (V.ii) or (V.ii)₂ according to an experimental protocol described in the literature (J. Org. Chem., (1995), 60, 5638-5642). The protected amine function is then deprotected under standard conditions in a strong acid medium (for example: trifluoroacetic acid or HCl in an organic solvent when it is a protective group of carbamate type), releasing the amine of general formula (V).

Obtaining the Thiazoles of General Formula (V) Intended for the Preparation of Compounds of General Formula (I)₃:

These compounds are obtained according to a method summarized in Diagram 3.4 below. The carboxamide of general formula (VII.ii) is firstly treated, for example, with Lawesson reagent or with (P₂S₅)₂ then the thiocarboxamide of general formula (VII.iii) obtained is reacted with the halogenated derivative of general formula (V.vii) (cf. Biorg. Med. Chem. Lett. (1996), 6(3), 253-258; J. Med. Chem. (1988), 31(10), 1910-1918; Tetrahedron Lett., (1993), 34 (28), 4481-4484; or J. Med. Chem. (1974), 17, 369-371; or also Bull. Acd. Sci. USSR Div. Chem. Sci. (Engl Transl) (1980) 29, 1830-1833). The protected amine of general formula (V.viii) thus obtained is then deprotected under standard conditions for a person skilled in the art (for example: trifluoroacetic acid or HCl in an organic solvent when Gp is a protective group of carbamate type).

Obtaining the Oxazoles of General Formula (V) Intended for the Preparation of Compounds of General Formula (I)₃:

These compounds are obtained according to a method summarized in Diagram 3.5 below. The carboxamide of general formula (VII.ii) is reacted with the halogenated derivative of general formula (V.vii). The protected amine of general formula (V.ix) thus obtained is then deprotected under standard conditions for a person skilled in the art in order to produce the compound of general formula (V) (for example: trifluoroacetic acid or HCl in an organic solvent when Gp is a protective group of carbamate type).

Preparation of the Ketonic Derivatives of General Formula (V.i) and of Certain α-bromoketonic Derivatives of General Formula (V.ii), (V.ii)₂, or (V.Vii)

The non-commercial ketonic derivatives of general formula (V.i) or their α-bromoketonic homologues are accessible from methods in the literature or similar methods adapted by a person skilled in the art. In particular:

-   -   when A represents an indolinyl or tetrahydroquinolyl radical,         the compounds of general formula (V.i) are accessible from         methods in the literature such as for example J. Med. Chem.         (1986), 29, (6), 1009-1015 or J. Chem. Soc., Perkin Trans. 1         (1992), 24, 3401-3406;

Alternatively, the compounds of general formula (V.ii) in which A represents an indolinyl or tetrahydroquinolyl radical in which R³³ represents H can be synthesized according to a protocol which is slightly modified compared to that described in J. Chem. Soc., Perkin Trans 1 (1992), 24, 3401-3406. This protocol is summarized in Diagram 3.6 below.

-   -   The indoline or tetrahydroquinoline (T represents —CH₂— or         —(CH₂)₂—) is protected using chloroacetyl chloride in order to         produce the compound of general formula (XVII) which is         subjected to a Friedel-Crafts reaction (substituted chloroacetyl         chloride of general formula (XVIII), in which B has the meaning         indicated previously, in a solvent such as carbon disulphide and         in the presence of aluminium chloride) in order to produce the         compound of general formula (XIX). Then the compound of general         formula (XIX) is hydrolyzed in the presence of acid, for example         an acetic acid/HCl mixture, in order to produce the compounds of         general formula (V.ii) in the form of a mixture of meta and para         isomers. These isomers can be separated by fractioned         crystallization from a solvent such as glacial acetic acid.     -   A person skilled in the art will know how to adapt the syntheses         described previously to the case where A represents an indolinyl         or tetrahydroquinolyl radical in which R³³ does not represent H.         For example, when R³³ represents an alkyl or aralkyl radical,         the protection and deprotection stages will be unnecessary.     -   when A represents a radical of 4-(4-hydroxyphenyl)-phenyl type,         the compounds of general formula (V.i) are accessible from         methods in the literature such as for example J. Org. Chem.,         (1994), 59(16), 4482-4489.     -   Alternatively, the compounds of general formula (V.i) and (V.ii)         in which A represents a radical of 4-(4-hydroxyphenyl)-phenyl         type are accessible for example by the method illustrated in         Diagram 3.7 below.

-   -   The compounds of general formula (V.i) or (V.ii), in which S₁,         S₂, S₃ and S₄ are chosen independently from a hydrogen atom and         OH, cyano, nitro, alkyl, alkoxy or —NR¹⁰R¹¹ as defined in         general formula (I), are prepared, Diagram 3.7, from the esters         of general formula (XX) (cf. in particular Chem. Lett. (1998),         9, 931-932 and Synthesis (1993), 8, 788-790). Of course, the         phenol or aniline functions resulting from the nature of the         R¹⁹, R²⁰, R²¹, S₁, S₂, S₃ and S₄ substituents can lead a person         skilled in the art to add to the stages represented in Diagram         3.7 protection stages (and, subsequently in the synthesis of the         compounds of general formula (I), deprotection stages) of these         functions so that they do not interfere with the remainder of         the chemical synthesis. The esters of general formula (XX) are         hydrolyzed in order to produce the acids of general formula         (XXI). The latter are then subjected to coupling with         N,O-dimethylhydroxylamine (Syn. Commun. (1995), 25(8), 1255;         Tetrahedron Lett. (1999), 40(3), 411-414) in a solvent such as         dimethylformamide or dichloromethane, in the presence of a base         such as triethylamine with dicyclohexylcarbodiimide or         1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and         hydroxybenzotriazole, in order to produce the intermediates of         general formula (XXII). The compounds of general formula (V.i)         are prepared from the compounds of general formula (XXII) by a         substitution reaction with MeLi (J. Med. Chem. (1992), 35(13),         2392). The bromoacetophenones of general formula (V.ii) are now         accessible from the acetophenone of general formula (V.i) under         the conditions described previously.     -   when A represents a carbazolyl radical, the compounds of general         formula (V.i) are accessible from methods in the literature such         as for example J. Org. Chem., (1951), 16, 1198 or Tetrahedron         (1980), 36, 3017.     -   Alternatively, the compounds of general formula (V.ii) in which         A represents a carbazolyl radical in which R⁹ represents H can         be synthesized according to a protocol which is slightly         modified with respect to that described for A=carbazolyl in         Tetrahedron (1980), 36, 3017. This method is summarized in         Diagram 3.8 hereafter:

-   -   The carbazole of general formula (XXIII) is protected using         acetic anhydride in order to produce the compound of general         formula (XXIV), which is subjected to a Friedel-Crafts reaction         (substituted chloroacetyl chloride of general formula (XVIII) as         defined previously in a solvent such as carbon disulphide and in         the presence of aluminium chloride) in order to produce the         compound of general formula (XXV). Then the acyl group         protecting the amine function is hydrolyzed in the presence of         acid, for example an AcOH/HCl mixture, in order to produce the         compound of general formula (V.ii). When A represents a         carbazolyl radical in which R⁹ represents alkyl or a —COR¹⁵         group (case not shown in Diagram 3.8), the initial acylation         stage is unnecessary and the last two stages of Diagram 3.8         allow the compounds of general formula (V.ii) to be obtained. Of         course, the phenol or aniline functions resulting from the         nature of the R⁴, R⁵, R⁶, R⁷ and R⁸ substituents can lead a         person skilled in the art to add to the stages represented in         Diagram 3.8 protection stages (and, subsequently in the         synthesis of the compounds of general formula (I), deprotection         stages) of these functions so that they do not interfere with         the remainder of the chemical synthesis.     -   when A represents a phenothiazinyl radical, the intermediates of         general formula (V.i) and (V.ii) are accessible from methods in         the literature: J. Heterocyclic. Chem. (1978), 15, 175-176 and         Arzneimittel Forschung (1962), 12, 48.     -   Alternatively, the intermediates of general formula (V.ii) in         which A represents a phenothiazinyl radical can be prepared         according to a protocol which is slightly modified with respect         to that described for the phenothiazinyl radical in Arzneimittel         Forschung (1962), 12, 48, which is summarized in Diagram 3.9         hereafter (see also the examples). The phenothiazine of general         formula (XXVI) is protected using chloroacetyl chloride in order         to produce the compound of general formula (XXVII), which is         then subjected to a Friedel-Crafts reaction (compound of general         formula (XVIII) in a solvent such as carbon disulphide in the         presence of aluminium chloride) in order to produce the compound         of general formula (XXVIII). During the last stage of the         process, hydrolysis with HCl/acetic acid is accompanied by a         halogen exchange and allows the chloroketone of general formula         (V.ii) to be obtained. Of course, the phenol or aniline         functions resulting from the nature of the R⁴, R⁵, R⁶, R⁷ and R⁸         substituents can lead a person skilled in the art to add to the         stages shown in Diagram 3.9 protection stages (and, subsequently         in the synthesis of the compounds of general formula (I),         deprotection stages) of these functions so that they do not         interfere with the remainder of the chemical synthesis.

-   -   when A represents a phenylaminophenyl radical, the compounds of         general formula (V.i) are accessible from methods in the         literature such as for example Chem. Commun., (1998), 15, (6)         1509-1510 or Chem. Ber., (1986), 119, 3165-3197, or similar         methods which a person skilled in the art will have adapted.     -   For example, the intermediates of general formula (V.i)a and         (V.ii)a in which A represents a phenylaminophenyl radical (which         correspond to the corresponding compounds of general formula         (V.i) and (V.ii) the aniline function of which has been         acetylated), can be prepared according to a protocol which is         slightly modified with respect to that described for the         phenylaminophenyl radical in Chem. Ber. (1986), 119, 3165-3197.         This protocol is summarized in Diagram 3.10 hereafter.

-   -   In the case (shown in Diagram 3.10) where the R⁹ radical of the         compound of general formula (I) to be synthesized is a hydrogen         atom or an acetyl group, the diphenylamine of general         formula (XX) formed after the coupling reaction in the presence         of CuI is protected by acetylation using, for example, acetic         anhydride in order to produce the compound of general formula         (V.i)a. In the case (not shown in Diagram 3.10) where the R⁹         radical of the compound of general formula (I) to be synthesized         is not a hydrogen atom or an acetyl radical, the acetylation         stage is replaced by a substitution stage of the aniline         according to standard methods known to a person skilled in the         art in order to produce the corresponding compound of general         formula (V.i). The compound of general formula (V.i)a (or (V.i),         in the case not shown in Diagram 3.10) is then subjected to a         bromination reaction using a bromination resin, PVPHP resin         (Poly(VinylPyridinium Hydrobromide Perbromide), described in J.         Macromol. Sci. Chem. (1977), A11, (3), 507-514, in order to         produce the compound of general formula (V.ii)a (or (V.ii), in         the case not shown in Diagram 3.10). Of course, the phenol or         aniline functions resulting from the nature of the R⁴, R⁵, R⁶,         R⁷ and R⁸ substituents can lead a person skilled in the art to         add to the stages shown in Diagram 3.10 protection stages (and,         subsequently in the synthesis of the compounds of general         formula (I), deprotection stages) of these functions so that         they do not interfere with the remainder of the chemical         synthesis. The deprotection of the acetylated aniline function         will be carried out in principle during the last stage of the         synthesis of the compounds of general formula (I).     -   when A represents a benzopyran or benzofuran radical as defined         in general formula (I) with R³² representing a hydrogen atom,         the intermediates of general formula (V.i) and (V.ii) are         accessible by the methods illustrated in Diagram 3.11 below.

-   -   The compounds of general formulae (V.i) and (V.ii), according to         Diagram 3.11, in which T is as defined above and Gp=protective         group, are prepared from the acids of general formula (XXX). The         acids of general formula (XXX) are subjected to coupling with         N,O-dimethylhydroxylamine (Syn. Commun. (1995), 25, (8), 1255;         Tetrahedron Lett. (1999), 40, (3), 411-414) in a solvent such as         dimethylformamide or dichloromethane, in the presence of a base         such as triethylamine with dicyclohexylcarbodiimide or         1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and         hydroxybenzotriazol, in order to produce the intermediates of         general formula (XXXI). The protection of the phenol function in         the form of a benzylated or tert-butyldimethylsilylated         derivative or by other protective groups (Gp) known to a person         skilled in the art is then carried out in order to produce the         compounds of general formula (XXXII). The compounds of general         formula (V.i) are prepared from the compounds of general         formula (XXXII) by a substitution reaction with a Grignard         reagent, MeMgCl (J. Het. Chem. (1990), 27, 1709-1712) or with         MeLi (J. Med. Chem. (1992), 35, 13). The bromoacetophenones of         general formula (V.ii) are now accessible from the acetophenone         of general formula (V.i) under previously described conditions.

Alternatively, the compound of general formula (V.ii) in which R³² represents a hydrogen atom or an alkyl radical can be prepared according to a process in only 3 stages (cf. Diagram 3.12—see also the examples). In this process, the bromination in the last stage of the compound of general formula (V.i) in order to produce the compound of general formula (V.ii) will preferably be carried out according to J. Am. Chem. Soc.(1999), 121, 24.

When A represents a substituted phenol radical, it can be necessary to use intermediates of general formula (V.ii) as defined previously the phenol function of which has been acetylated (hereafter designated as compounds of general formula (V.ii)b). In particular:

-   -   when A represents a 4-hydroxy-3,5-diisopropylphenyl radical, the         homologous α-bromoketonic derivatives of the compound of formula         (V.ii) the phenol function of which is protected by an acetyl         radical can be prepared as summarized in Diagram 3.13 hereafter.

2,6-diisopropylphenol is acetylated according to methods known to a person skilled in the art, for example by reacting it with acetic acid in the presence of trifluoroacetic acid anhydride or with acetyl chloride in the presence of a base such as for example K₂CO₃. The acetylated homologue of 2,6-diisopropylphenol is then subjected to a Fries rearrangement in the presence of aluminium chloride in a solvent such as nitrobenzene in order to produce the compound of formula (V.i). Then the compound of formula (V.i) is acetylated in order to produce the compound of formula (V.i)b. Bromination is then carried out with CuBr₂ as previously described in order to produce the compound of formula (V.ii)b. The deprotection stage to release the phenol function will occur subsequently in the synthesis of the compounds of general formula (I) (at the time considered most appropriate by a person skilled in the art).

-   -   when A represents a radical of dimethoxyphenol type, the         compounds of general formula (V.ii)b can be prepared in a         similar fashion to the synthesis described for the compound of         formula (V.ii)b derived from 2,6-diisopropylphenol, optionally         with a few minor modifications within the scope of a person         skilled in the art. For example, when A represents the         3,5-dimethoxy-4-hydroxyphenyl radical, the corresponding         α-bromoketonic derivative of formula (V.ii)b can be prepared,         for example, as indicated in Diagram 3.13 from the commercial         compound of formula (XXXV):

The compounds of general formula (V.ii)₂ in which A and B are as defined previously can be prepared according to the method summarized in Diagram 3.15 hereafter.

The acids of general formula (XXXVI) are subjected to coupling with 5 N,O-dimethylhydroxylamine (Syn. Commun. (1995), 25, (8), 1255; Tetrahedron Lett. (1999), 40, (3), 411-414) in a solvent such as dimethylformamide or dichloromethane, in the presence of a base such as triethylamine with dicyclohexylcarbodiimide or 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and hydroxybenzotriazol, in order to produce the intermediates of general formula (XXXVII). The compounds of general formula (V.i)₂ are prepared from the compounds of general formula (XXXVII) by a substitution reaction with lithium compound or magnesium compound derivatives of general formula B-M in which M represents Li or MgHal (Hal=I, Br or Cl) in solvents such as ether or anhydrous tetrahydrofuran. The α-bromo- or α-chloroketones of general formula (V.ii)₂ can now be accessed from the ketones of general formula (V.i)₂ under the conditions previously described.

Moreover, the non commercial α-halogenoketonic derivatives of general formula (V.vii) are accessible from methods in the literature. In particular, they can be obtained according to a procedure summarized in Diagram 3.16.

The protected amino acids of general formula (XXXVIII) are obtained by protection of the corresponding amino acids by a group of carbamate type according to methods known to a person skilled in the art. The acids of general formula (XXXVIII) are then subjected to coupling with N,O-dimethylhydroxylamine (Syn. Commun. (1995), 25, (8), 1255; Tetrahedron Lett. (1999), 40, (3), 411-414) in a solvent such as dimethylformamide or dichloromethane, in the presence of a base such as triethylamine with dicyclohexylcarbodiimide or 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and hydroxybenzotriazole, in order to produce the intermediates of general formula (XXXIX). The compounds of general formula (XLI) are prepared from the compounds of general formula (XXXIX) by a substitution reaction with lithium compound or magnesium compound derivatives of general formula (XL) (in which Hal=I, Br or Cl) in solvents such as ether or anhydrous tetrahydrofuran. The bromo or chloroacetophenones of general formula (V.vii) are now accessible from the acetophenone of general formula (XLI) under the conditions previously described.

Alternatively, a person skilled in the art can also use or adapt the syntheses described in Angew. Chem. Int. (1998), 37 (10), 411-414, Liebigs Ann. Chem. (1995), 1217 or Chem. Pharm. Bull. (1981), 29(11), 3249-3255.

Preparation of the Acid Derivatives of General Formula (V.iii)

The acid derivatives of general formula (V.iii) can be obtained, Diagram 3.17, directly by reaction of the commercial amino acid of general formula (V.vi) with the compounds of (ar)alkylchloroformate or di(ar)alkylcarbonate type (Δ represents an alkyl or benzyl radical) under standard conditions known to a person skilled in the art.

Preparation of the Compounds General Formula (V.v)

The thiocarboxamides of general formula (V.v) can be obtained in three stages starting from the compounds of general formula (V.vi) as indicated in the Diagram 3.18 below. The amine function of the amino acid of general formula (V.vi) is firstly protected under standard conditions with tBu-O—CO—Cl or (tBu-O—CO)₂O (or other protective groups known to a person skilled in the art), then the intermediate obtained is converted to its corresponding amide by methods described in the literature (cf. for example, J. Chem. Soc., Perkin Trans. 1, (1998), 20, 3479-3484 or the PCT Patent Application WO 99/09829). Finally, the carboxamide is converted to the thiocarboxamide of general formula (V.v), for example by reaction with Lawesson reagent in a solvent such as dioxane or tetrahydrofuran at a temperature preferably comprised between ambient temperature and the reflux temperature of the mixture, or also using (P₂S₅)₂ under standard conditions for a person skilled in the art.

Alternatively, the thiocarboxamides of general formula (V.v) can also be obtained, Diagram 3.19, by the addition of H₂S on the corresponding cyano derivatives of general formula (V.x) under standard conditions known to a person skilled in the art.

Preparation of the Acids of General Formula (VI) Preparation of the Acid Derivatives of Thiazoles of General Formula (VI)

The acids of general formula (VI) derived from thiazoles can be prepared according to the procedures represented in Diagram 4.1 below.

The carboxamides of general formula (VII.ii) are treated under standard conditions in order to produce the thiocarboxamide of general formula (VII.iii), for example by Lawesson reagent or also using (P₂S₅)₂ under standard conditions for a person skilled in the art. Alternatively the acid of general formula (VII.i) is activated by the action of 1,1′-carbonyldiimidazole then treated with methylamine in an aprotic polar solvent such as for example tetrahydrofuran. The carboxamide intermediate obtained is converted to the thiocarboxamide of general formula (VI.i) under standard conditions, for example using Lawesson reagent or also using (P₂S₅)₂ under standard conditions for a person skilled in the art. The thiocarboxamide of general formula (VII.iii) or (VI.i) is then reacted with the compound of general formula (VI.ii), for example while heating at reflux in a solvent such as benzene, dioxane or dimethylformamide. The ester of general formula (VI.iii) obtained can then be saponified by the action of a base such as for example potash in alcoholic medium or LiOH in tetrahydrofuran in order to produce the acid of general formula (VI).

Preparation of the Acid Derivatives of Oxazoles of General Formula (VI)

The acids of general formula (VI) derived from oxazoles can be prepared according to a procedure represented in Diagram 4.2 below.

The carboxamides of general formula (VII.ii) are reacted with the compound of general formula (VI.ii) while heating, for example at reflux, in the absence or in the presence of a solvent such as dimethylformamide. The ester of general formula (VI.iv) obtained can then be saponified by the action of a base such as for example potash in alcoholic medium or LiOH in tetrahydrofuran in order to produce the acid of general formula (VI).

Preparation of the Acid Derivatives of Isoxazolines of General Formula (VI)

The acid derivatives of isoxazolines of general formula (VI), used in the preparation of compounds of general formula (I)₄, can be prepared according to a procedure represented in Diagram 4.3 below.

The acids of general formula (VI) derived from isoxazolines can be prepared as follows: the commercial aldehydes of general formula (VI.v) are reacted with hydroxylamine hydrochloride. The oxime of general formula (VI.vi) thus obtained is activated in the form of oxime chloride, of general formula (VI.vii), by reaction with N-chlorosuccinimide in DMF before reacting with the esters of general formula (VI.viii) (in which Alk represents an alkyl radical) in order to produce the isoxazoline derivatives according to an experimental protocol described in the literature (Tetrahedron Lett., 1996, 37 (26), 4455; J. Med. Chem., 1997, 40, 50-60 and 2064-2084). Saponification of the isoxazolines of general formula (VI.ix) is then carried out in a standard fashion (for example by the action of KOH in an alcoholic solvent or LiOH in a solvent such as tetrahydrofuran) in order to produce the acid derivative of general formula (VI).

The non-commercial unsaturated esters of general formula (VI.x) can be prepared according to the methods described in the literature (J. Med. Chem., 1987, 30, 193; J. Org. Chem., 1980, 45, 5017).

Preparation of the Thiazoles and Oxazoles of General Formula (VII)

General Outline

The acids of general formula (VII.i), Diagram 5.1, are converted to the corresponding carboxamides of general formula (VII.ii) by methods described in the literature (cf. for example, J. Chem. Soc., Perkin Trans. 1, (1998), 20, 3479-3484 or the PCT Patent Application WO 99/09829). The compounds of general formula (VII) can then be obtained in a standard fashion according to the procedures represented in Diagrams 5.2 and 5.3 (thiazoles) and Diagram 5.4 (oxazoles) hereafter.

This synthesis route is useful for then preparing the compounds corresponding to general sub-formulae (I)₁ and (I)₃.

Obtaining the Thiazoles of General Formula (VII)

When R¹ and R² both represent H, the thiazoles of general formula (VII) intended for the preparation of compounds of general formula (I)₃ can be prepared according to the method summarized in Diagram 5.2. The carboxamide of general formula (VII.ii) is converted to the corresponding thiocarboxamide of general formula (VII.iii) in the presence of Lawesson reagent in a solvent such as dioxane or benzene at a temperature preferably comprised between ambient temperature and that of reflux of the mixture. The thiocarboxamide of general formula (VII.iii) is then treated with the α-halogenoketoester of general formula (VII.iv) in which Alk represents an alkyl radical (for example methyl, ethyl or tert-butyl), in order to produce the ester of general formula (VII.v), which is reduced to the corresponding alcohol of general formula (VII.vi), for example by the action of lithium aluminium hydride or diisobutylaluminium hydride in a solvent such as tetrahydrofuran. This latter can then be converted to a halogenated derivative of general formula (VII) according to the methods known to a person skilled in the art, for example, in the case of a brominated derivative (L=Br), by reaction with CBr₄ in the presence of triphenylphosphine in dichloromethane at ambient temperature.

The thiazoles of general formula (VII) intended for the preparation of compounds of general formula (I)₁ can be prepared according to the method summarized in Diagram 5.3. The cyano derivative of general formula (VII.vii) in which Gp′ is a protective group for an alcohol function (for example a benzyl or CO-ρ group in which ρ represents alkyl, for example methyl or tert-butyl) is converted to the corresponding thiocarboxamide of general formula (VII.viii) by the action of H₂S in a solvent such as ethanol in the presence of triethanolamine at a temperature preferably comprised between ambient temperature and that of reflux of the mixture. The thiocarboxamide of general formula (VII.viii) is then treated with the α-halogenoketone of general formula (VII.ix) in order to produce the compound of general formula (VII.x), which is deprotected in order to produce the corresponding alcohol of general formula (VII.xi) according to methods known to a person skilled in the art (for example when Gp′ is a protective group of acetate type, this is removed in situ by the action of an aqueous solution of sodium carbonate). This latter can then be converted to a halogenated derivative of general formula (VII) according to the methods known to a person skilled in the art, for example, in the case of a brominated derivative (L=Br), by reaction with CBr₄ in the presence of triphenylphosphine in dichloromethane at ambient temperature.

Obtaining the Oxazoles of General Formula (VII)

When R¹ and R² both represent H, the oxazoles of general formula (VII) intended for the preparation of compounds of general formula (I)₃ can be prepared according to the method summarized in Diagram 5.4. The carboxamide of general formula (VII.ii) is treated with the α-halogenoketoester of general formula (VII.iv) in which Alk represents an alkyl radical (for example methyl, ethyl or tert-butyl), in order to produce the ester/acid of general formula (VII.xii). This latter is reduced to the corresponding alcohol of general formula (VII.xiii), for example by the action of lithium and aluminium hydride or diisobutylaluminium hydride in a solvent such as tetrahydrofuran when one starts from the ester or by the action of diborane in tetrahydrofuran when one starts from the acid. This latter can then be converted to a halogenated derivative of general formula (VII) according to methods known to a person skilled in the art, for example, in the case of a brominated derivative (L=Br), by reaction with CBr₄ in the presence of triphenylphosphine in dichloromethane at ambient temperature.

Preparation of the Acids of General Formula (VII.i)

The non-commercial acids of general formula (VII.i) are accessible from methods in the literature. In particular:

-   -   when A represents a phenothiazinyl radical, the acids of general         formula (VII.i) are accessible from methods in the literature         such as for example J. Med. Chem. (1992), 35, 716-724, J. Med.         Chem. (1998), 41, 148-156; Synthesis (1988) 215-217; or J. Chem.         Soc. Perkin. Trans. 1 (1998), 351-354;     -   when A represents an indolinyl radical, the acids of general         formula (VII.i) are accessible from methods in the literature         such as for example J. Het. Chem. (1993), 30, 1133-1136 or         Tetrahedron (1967), 23, 3823;     -   when A represents a phenylaminophenyl radical, the acids of         general formula (VII.i) are accessible from methods in the         literature such as for example J. Amer. Chem. Soc. (1940), 62,         3208; Zh. Obshch. Khim. (1953), 23, 121-122 or J. Org. Chem.         (1974), 1239-1243;     -   when A represents a carbazolyl radical, the acids of general         formula (VII.i) are accessible from methods in the literature         such as for example J. Amer. Chem. Soc., (1941), 63,         1553-1555; J. Chem. Soc. (1934), 1142-1144; J. Chem. Soc.         (1945), 945-956; or Can. J. Chem. Soc. (1982), 945-956; and     -   when A represents a radical of 4-(4-hydroxyphenyl)-phenyl type,         reference will be made for example to the following publication:         Synthesis (1993) 788-790.         Preparation of the Compounds of General Formula (VIII)

When R¹ and R² both represent H, the protected amino acids of general formula (VIII) are either commercial, or obtained by protection of commercial amino acids by a group of carbamate type according to the methods known to a person skilled in the art.

When at least one of R¹ and R² is not H, and n=0, the protected amino acids of general formula (VIII) are obtained in one stage, Diagram 6.1, by alkylation, in a solvent such as tetrahydrofuran and at low temperature, of commercial compound of general formula (VIII.i) using 3 equivalents of butyllithium and approximately one equivalent of the halogenated derivative of general formula (VIII.ii) in which R¹ represents a radical of alkyl, cycloalkyl, cycloalkylalkyl or arylalkyl type and Hal a halogen atom. Depending on the case, a second alkylation (not represented in Diagram 6.1) can be carried out in a similar fashion, thus allowing the compounds of general formula (VIII) to be obtained in which neither R¹ nor R² represents H.

The cyano derivative of general formula (X.ii) is treated, Diagram 8.2, with H₂S in order to produce the thiocarboxamide of general formula (X.iii), which, condensed with the compound of general formula (V.ii), allows the compound of general formula (X) to be obtained. The reaction conditions are similar to those described above (Diagram 5.3) for this type of synthesis.

Preparation of the Acids of General Formula (XXXVI)

The non commercial acids of general formula (XXXVI) are accessible from methods in the literature or similar methods adapted by a person skilled in the art. In particular:

-   -   when A represents a phenothiazinyl radical, the acids of general         formula (XXXVI) are accessible from methods in the         literature: J. Org. Chem., (1956), 21, 1006; Chem.

Abstr., (1968), 68, 68730×; or by         adaptation of these methods by a person skilled in the art;     -   when A represents a radical of 4-(4-hydroxyphenyl)-phenyl type,         the acids of general formula (XXXVI) can be accessed from         methods in the literature such as for example Tetrahedron Lett.

Of course, the phenol, amine or aniline functions resulting from the nature of the substituents on the A radical of the compounds of general formula (XXXVI) can lead a person skilled in the art to add protection/deprotection stages of these functions to the stages described so that they do not interfere with the rest of the chemical synthesis.

Unless defined otherwise, all the technical and scientific terms used here have the same meaning as that usually understood by an ordinary specialist in the field to which this invention belongs. Likewise, all publications, patent applications, all patents and all other references mentioned here are incorporated by way of reference.

The following examples are presented to illustrate the above procedures and must in no case be considered as limiting the scope of the invention.

EXAMPLES Example 1 4-[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl]-N-methyl-2-thiazolemethanamine

This product is obtained according to the procedure described in the PCT Patent Application WO 98/58934. Alternatively, it can also be prepared according to the method described below.

1.1) N-Boc-sarcosinamide

15.0 g (0.120 mol) of sarcosinamide hydrochloride (N-Me-Gly-NH₂.HCl) is dissolved in dichloromethane containing 46.2 ml (0.265 mol) of diisopropylethylamine. The mixture is cooled down to 0° C. then Boc-O-Boc (28.8 g; 0.132 mol) is added in fractions and the mixture is stirred overnight at ambient temperature. The reaction medium is then poured into ice-cooled water followed by extraction with dichloromethane. The organic phase is washed successively with a 10% aqueous solution of sodium bicarbonate and with water, then finally with a saturated solution of sodium chloride. The organic phase is then dried over magnesium sulphate, filtered and concentrated under vacuum. The product obtained is purified by crystallization from diisopropyl ether in order to produce a white solid with a yield of 72%. Melting point: 103° C.

1.2) 2-{[(1,1-dimethylethoxy)carbonyl]methyl}amino-ethanethioamide

16.0 g (0.085 mol) of intermediate 1.1 is dissolved in dimethoxyethane (500 ml) and the solution obtained is cooled down to 5° C. Sodium bicarbonate (28.5 g; 0.34 mol) then, in small portions, (P₂S₅)₂ (38.76 g; 0.17 mol) are added. The reaction medium is allowed to return to ambient temperature under stirring over 24 hours.

Pharmacological Study of the Products of the Invention

Study of the Effects on the Bond of a Specific Ligand of MAO-B, [³H]Ro 19-6327

The inhibitory activity of the products of the invention is determined by measurement of their effects on the bond of a specific ligand of MAO-B, [³H]Ro 19-6327.

a) Mitochondrial Preparation of the Cortex of Rats

The mitochondrial preparation of the cortex of rats is carried out according to the method described in Cesura A M, Galva M D, Imhof R and Da Prada M, J. Neurochem. 48 (1987), 170-176. The rats are decapitated and their cortex is removed, homogenized in 9 volumes of a 0.32 M sucrose buffer, buffered to pH 7.4 with 5 mM of HEPES, then centrifuged at 800 g for 20 minutes. The supernatants are recovered and the pellets are washed twice with the 0.32 M sucrose buffer as previously. The collected supernatants are centrifuged at 10000 g for 20 minutes. The pellets obtained are suspended in a Tris buffer (50 mM Tris, 130 mM NaCl, 5 mM KCl, 0.5 mM EGTA, 1 mM MgCl₂, pH 7.4) and centrifuged at 10000 g for 20 minutes. This stage is repeated twice, and the final pellet, corresponding to the mitochondrial fraction, is stored at −80° C. in the Tris buffer. The proteinic content of the preparation is determined by the Lowry method.

b) Bond of [³H]Ro 19-6327

100 μl of the mitochondrial preparation (2 mg protein/ml) are incubated for 1 hour at 37° C. in an Eppendorf tube, in the presence of 100 μl of [³H] Ro 19-6327 (33 nM, final concentration) and 100 μl of Tris buffer containing or not containing the inhibitors. The reaction is stopped by the addition of 1 ml of unlabelled Tris buffer into each tube, then the samples are centrifuged for 2 minutes at 12000 g. The supernatants are removed by suction and the pellets washed with 1 ml of Tris buffer. The pellets are then solubilized in 200 μl of sodium dodecyl sulphate (20% weight/volume) for 2 hours at 70° C. The radioactivity is determined by counting the samples using liquid scintillation.

Study of the Effects on Lipidic Peroxidation of the Cerebral Cortex of the Rat

The inhibitory activity of the products of the invention is determined by measuring their effects on the degree of lipidic peroxidation, determined by the concentration of malondialdehyde (MDA). The MDA produced by peroxidation of unsaturated fatty acids is a good indication of lipidic peroxidation (H Esterbauer and K H Cheeseman, Meth. Enzymol. (1990) 186: 407-421). Male Sprague Dawley rats weighing 200 to 250 g (Charles River) were sacrificed by decapitation. The cerebral cortex is removed, then homogenized using a Thomas potter in a 20 mM Tris-HCl buffer, pH=7.4. The homogenate is centrifuged twice at 50000 g for 10 minutes at 4° C. The pellet is stored at −80° C. On the day of the experiment, the pellet is resuspended at a concentration of 1 g/15 ml and centrifuged at 515 g for 10 minutes at 4° C. The supernatant is used immediately to determine the lipidic peroxidation. The homogenate of rat's cerebral cortex (500 μl) is incubated at 37° C. for 15 minutes in the presence of the compounds to be tested or of the solvent (10 μl). The lipidic peroxidation reaction is initiated by adding 50 μl of FeCl₂ at 1 mM, EDTA at 1 mM and ascorbic acid at 4 mM. After incubation for 30 minutes at 37° C., the reaction is stopped by adding 50 μl of a solution of hydroxylated di-tert-butyl toluene (BHT, 0.2%). The MDA is quantified using a colorimetric test, by reacting a chromogenic reagent (R), N-methyl-2-phenylindol (650 μl) with 200 μl of the homogenate for 1 hour at 45° C. The condensation of an MDA molecule with two molecules of reagent R produces a stable chromophore the maximum absorbence wavelength of which is equal to 586 nm (Caldwell et al., European J. Pharmacol. (1995), 285, 203-206). The compounds of Examples 1 to 3, 6 to 17,20 to 30, 320, 321, 323, 331, 332, 350, 352 to 377, 399 to 411, 413 to 435, 437 to 442, 463 to 467, 470 to 474, 476, 477 and 480 to 489 described above show an IC₅₀ lower than 10 μM.

Bond Test on the Cerebral Sodium Channels of the Cortex of the Rat

The test consists in measuring the interaction of the compounds vis-à-vis the bond of tritiated batrachotoxin on the voltage-dependent sodium channels according to the protocol described by Brown (J. Neurosci. (1986), 6, 2064-2070).

Preparation of Homogenates of Cerebral Cortices of the Rat

The cerebral cortices of Sprague-Dawley rats weighing 230-250 g (Charles River, France) are removed, weighed and homogenized using a Potter homogenizer provided with a teflon piston (10 strokes) in 10 volumes of isolation buffer the composition of which is as follows (sucrose 0.32 M; K₂HPO₄ 5 mM; pH 7.4). The homogenate is subjected to a first centrifugation at 1000 g for 10 minutes. The supernatant is removed and centrifuged at 20000 g for 15 minutes. The pellet is taken up in the isolation buffer and centrifuged at 20000 g for 15 minutes. The pellet obtained is resuspended in incubation buffer (HEPES 50 mM; KCl 5.4 mM; MgSO₄ 0.8 mM; glucose 5.5 mM; choline chloride 130 mM pH 7.4) then aliquoted and stored at −80° C. until the day of assay. The final protein concentration is comprised between 4 and 8 mg/ml. The assay of proteins is carried out using a kit marketed by BioRad (France).

Measurement of the Bond of Tritiated Batrachotoxin

The bond reaction is carried out by incubating for 1 hour 30 minutes at 25° C. 100 μl of homogenate of rat cortex containing 75 μg of proteins with 100 μl of [³H] batrachotoxin-A 20-alpha benzoate (37.5 Ci/mmol, NEN) at 5 nM (final concentration), 200 μl of tetrodotoxin at 1 μM (final concentration) and scorpion venom at 40 μg/ml (final concentration) and 100 μl of incubation buffer alone or in the presence of the products to tested at different concentrations. The non-specific bond is determined in the presence of 300 μM of veratridine and the value of this non-specific bond is subtracted from all the other values. The samples are then filtered using a Brandel (Gaithersburg, Md., USA) using Unifilter GF/C plates pre-incubated with 0.1% of polyethylene imine (20 μl/well) and rinsed twice with 2 ml of filtration buffer (HEPES 5 mM; CaCl₂ 1.8 mM; MgSO₄ 0.8 mM; choline chloride 130 mM; BSA 0.01%; pH 7.4). After having added 20 μl of Microscint 0®, the radioactivity is counted using a liquid scintillation counter (Topcount, Packard). The measurement is carried out in duplicate. The results are expressed as a % of the specific bond of tritiated batrachotoxin relative to the control.
